This brings you back to 16.
Whenever you times a number by something and then divide it by the same number, the answer will always go back to where it started.
If the x=4, then its equivelent to 12 + 4, which equals 16.
1 x 16, 2 x 8, 4 x 4, 8 x 2, 16 x 1.

To find what equals 16 when added to 20, you can set up the equation: 20 + x = 16. Solving for x, you subtract 20 from both sides, yielding x = 16 - 20, which simplifies to x = -4. Therefore, 20 plus -4 equals 16.
If the x=4, then its equivelent to 12 + 4, which equals 16.
20 - 4 = 16
4 x 4 = 16
16 = 1 x 16 = 2 x 8 = 4 x 4

1 x 16, 2 x 8, 4 x 4, 8 x 2, 16 x 1.
1 x 16, 2 x 8, 4 x 4, 8 x 2, 16 x 1 = 16
3x + 4 = 16 3x = 16 - 4 x = 12/3 x = 4
